"Our progress has been slow and has lacked urgency," one lawmaker said. The service's acquisition chief made the comments a day after Secretary Frank Kendall told lawmakers the latest ARRW test failed. Secretary Frank Kendall confirmed this month's ARRW hypersonic test wasn't successful, and said the service is more committed to another weapon. The Air Force said in a release that "several" objectives were met, but refused to detail further the results of the test. The Cyber Resiliency Office for Weapon Systems works with acquisition and test teams to ensure old and new platforms are protected against cyber threats. The first unit equipped is scheduled for early 2024. The light machine gun will retain its M250 designation. One of the earliest test flights took place in 2010. The weapons are going to infantry, scouts, combat engineers and special operations.
